Anti-Tangle Cable Swivel
Say goodbye to tangled cords. An anti-tangle swivel lets the robot move 360° around your pool without the cord getting tangled, so you can sit back while it cleans. Learn more ›
Warranty Coverage
A robot is only as good as its warranty. The Dolphin Nautilus CC is backed by a 1-year warranty, while the Aquabot X4 carries a 2-year warranty. Buying through an Authorized Dealer like Poolbots gets you the full manufacturer warranty — never pro-rated or limited by cleaning cycles — plus a 30-day in-pool trial with no restocking fees.
